Ro48-6791 is a drug, a benzodiazepine derivative developed by Hoffman-LaRoche in the 1990s.[1]

Ro48-6791 was developed as an alternative to the short-acting imidazobenzodiazepine midazolam, for use in induction of anaesthesia and conscious sedation for minor invasive procedures. Ro48-6791 has properties similar to those of to midazolam, being water-soluble, with a fast onset and short duration of action. It is 4-6x more potent than midazolam,[2] and slightly shorter acting,[3] and produces similar side effects such as sedation and amnesia.

It was tested up to Phase II human trials, but while it produced less respiratory depression than propofol, it had a longer recovery time and was deemed not to have any significant advantages over the older drug.[4] Similarly when Ro48-6791 was compared to midazolam, it had similar efficacy, higher potency and a shorter recovery time, but produced less of a synergistic effect on opioid-induced analgesia and produced more severe side effects such as dizziness after the procedure.[5] Consequently, it was dropped from clinical development,[6] although it is still used in scientific research.[7]
